You can not be absolutely certain how big your baby will be at birth, but the average newborn comes into the world at about 3 pounds and measuring about 50 centimeters.

The bones of the baby’s head are not yet fully attached, which will allow them to overlap a little if the passage of the birth canal is tight. This bone flexibility is the reason why many children are born with a head that resembles a cone. If it is the case of your child, do not worry, since this is perfectly normal and temporary.

Week 40 – 2nd day


Birth day should be scheduled for this week, but it is normal for it to last for up to two more, especially if it is the first child. Many babies take longer than others to want to get out of the “nest”.

From now on, be especially attentive to the baby’s movements. Practice this observation by lying on the left half hour after breakfast, lunch and dinner. Lie down for an hour. Your baby should move at least three times during this time. This is a sign of fetal well-being. If not, contact your doctor.

You must be very anxious. Your baby should be here any minute. The maternity suitcase is ready, the photo camera in hand and the belly is huge and heavy. If the water bag breaks, do not despair. After the ruptured pouch, the contractions may be slow to appear. Call your doctor to get directions and move to the hospital.

Week 40 – 3rd day

Your baby should be about 3.5 pounds. From head to toe, about 48 centimeters, on average. Everything confers and there is no doubt: the big day is coming for your baby. He now begins to release corticosteroids, a series of different hormones that make the muscles of the uterus contract. From a tiny embryo, he was able to evolve and, little by little, he became a human being endowed with intelligence and great abilities.

Week 40 – 4th day

Your baby is curled up tightly inside the womb and is all covered by Vernix, a whitish substance. Even after he is born, his little body will remain shrunken for a few weeks in a fetal position. He is well accustomed to keeping his legs and arms close to his body.

Week 40 – 5th day

Organs and body systems are ready for life outside the womb. It also stored starch in the liver, to be converted to glucose after birth, and has extra fluids on board as well. He is well equipped to withstand the birth and the first day as the milk from his chest begins to flow.

Week 40 – 6th day

Suitcase in the trunk, the embellishment of the maternity door in hand, and the anxious dad walking back and forth. Now it’s only a matter of hours.

At any moment, the most intense contractions will appear. When you notice a pattern in the interval between them, call your doctor or go to the maternity ward. Soon you will be breastfeeding and giving the baby a bath. Exciting!

Week 40 – 7th day

The birthing

Shortly after the first deep sigh, comes the lament worthy of an opera singer. The sound of baby crying is a paradoxical experience. On the one hand, no one likes to hear a child feeling fear or discomfort, on the other, a loud and strong cry means that she is breathing well. But do not expect to see tears yet.

Your lacrimal glands will not tear until they are a few weeks old. And even if your baby does not give this classic cry, do not be alarmed: some children do not cry at birth. The most important thing is for him to start breathing. From here, your baby is ready for a new journey. And this time, by your side, not inside you.

The end of pregnancy represents the beginning of a new journey of discovery, learning and joy. It is also the beginning of a new life that will need all your affection. Congratulations, Mom, be very happy!

Tips of Pregnancy

Before certain signs and symptoms, you should prepare to go to the hospital / maternity:

Regular, painful, and intense contractions

The contractions are a sign that she has begun to dilate: rhythmic contractions every 10 minutes or every 5 minutes , accompanied by pains, rupture of the pouch or vaginal bleeding are one of the signs of the onset of labor.

Ruture of the water bag

The rupture of the bag of water causes the amniotic fluid to pass through the vagina, due to the rupture of the membranes that surround the baby. The liquid may break out slowly or suddenly and in large quantities. Normally, the liquid is clear and transparent.

What you should always have at hand

  • The maternity suitcase ( yours and your baby’s ) and the stem cell collection kit ;
  • The contacts of your companion, the doctor and the maternity / hospital where you planned to have the birth
  • The Pregnancy Health Bulletin.

Phases of normal labor

The labor is divided into three phases that correspond to the dilation of the cervix, baby expulsion and expulsion of the placenta or dequitadura, respectively.

1st stage of labor

The first phase of labor is subdivided into 3 that correspond to different moments of dilation of the cervix. Progressively, contractions become more frequent, longer and stronger.

As soon as you become regular (about 3 contractions every 10-15 minutes), you go into labor. It’s time to go to the maternity / hospital. At the end of this phase, you reach the maximum dilation (10 cm) and you will feel an irresistible urge to force yourself to expel the baby.

2nd stage of labor

The second phase of labor begins when it reaches 10 cm of dilatation. Already in the delivery room and with the epidural , if that was your choice for pain management. With each new push, your baby descends a little further down the birth canal, moving closer and closer to the outside.

The maximum duration of this period is 2 hours for nulliparous (first-time mother) and 1 hour for multiparous (mother who has had a previous birth). If the mother took epidural analgesia, these maxima should be added for 1 hour.

3rd stage of labor

The 3rd phase and final phase of labor begins immediately after the birth of the baby and ends with the expulsion of the placenta (placental delivery of the placenta ) and membranes after its detachment.

There may be a need to suture the perineum if it has been torn by pressure exerted by the baby or cut ( episiotomy ) to widen the vaginal canal and facilitate expulsion of the baby.

Puerperium or postpartum

The first 6 to 8 weeks postpartum are considered a period of recovery ( puerperium ), during which your body undergoes a series of changes to return to the pre-pregnancy state.

The puerperal consultation (or postpartum review visit) is usually scheduled at the last pregnancy surveillance visit and performed between the 4th and 6th weeks after childbirth.

First days after delivery

The first days after delivery are full of emotions. The happiness of having your baby in your arms brings together other feelings such as the fear of not being able to breastfeed, the doubts about the care you take when you go home or the tiredness and physical recovery you are going through.

Remember that your body and mind need time to assimilate everything that happened in the last weeks of pregnancy and the birth of your baby. Being able to deal with all recent events requires calm, support and, above all, seeking to enjoy all that has entered into your life again.


  1. Vaginal discharge similar to the menstrual period, referred to as llocum , initially bright red (in the first 3-4 days after delivery), then pinkish or brownish and finally yellowish or colorless
  2. Fatigue
  3. Pain and discomfort of the perineum or cesarean section
  4. Constipation and hemorrhoids
  5. Gradual weight loss
  6. Decreased swelling
  7. Sensitive and sore nipples
  8. Back and joint pain
  9. Hair loss .


  1. Oscillations between states of enthusiasm and melancholy
  2. Feeling of being overwhelmed, feeling that you can not respond to all requests, which can cause frustration and anxiety
  3. Decreased interest in sex
  4. Symptoms such as mood swings, constant sadness, negative thoughts about yourself and your baby, irritability and lack of patience, among others, can be a warning for postpartum depression and should be shared with your doctor.


Does your child delay birth? Do not worry, 65% of births are delayed, 30% advance and only 5% occur on the expected date of delivery.
This is because the calculated date for delivery from the last menstrual period is statistical and does not consider the innumerable variables specific to female ovulation.

If you are worried, discuss this with your gynecologist: If your baby is lazy, your doctor may encourage birth.
